[Uptown] Erb/Bridgeport/Caroline/Albert Reconstruction

How do we know that this improvement was caused by the change from one-way to two-way streets? 

Locally in KItchener, crime has fallen and property values have increased in Cedar Hill.  Was there some hidden one-way street in the Cedar Hill neighbourhood that was converted to two-way?  Or could it possibly be that there are other possible causes for drops in crime and improvements in property values?

The argument is that converting one-way streets to two-way has myriad benefits. It is not that some or all of those benefits can only be achieved by converting one-way streets to two-way.What does Cedar Hill have to do with it? Property values increase, and crime falls, in all kinds of neighbourhoods...but what would most of those have to do with a discussion about converting one-way streets?

Sorry, I probably should not have used sarcasm in comment. 

The point is that there are many possible reasons for reductions in crime, and for increases in property values.  The blog author assumes all of that is due to the change from a pair of one-way streets to two-way streets.  Just because the improvements in the crime rate and the property values were subsequent to making the streets two-way, does not automatically mean that those improvements were CAUSED by that change.
